If you say so, may be you are building in-source.
Did you try out-of-source build?
http://www.cmake.org/Wiki/CMake_FAQ#Out-of-source_build_trees

If you are already doing out-of-source build and want to exclude some other
files then CPACK_SOURCE_IGNORE_FILES should be the way to go.

Yes, unfortunately there is no "CPACK_SOURCE_INCLUDE_FILES".

You'll have to implement CPack time copy, you may do that inside a
CPACK_PROJECT_CONFIG_FILE.
see: http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#Overall_usage_.28common_to_all_generators.29

However I don't think it's the best solution in your case.

Like I said, out-of-source, should be the easy way to achieve what you want.

Another way to have a "clean" copy would be to use your VCS
e.g.
svn export + tar/zip/.... in a custom_command
cvs export + tar/zip/.... in a custom_command
git archive
...
